Two PAGES working groups, PALeo constraints on SEA level rise and PAGES-PMIP Working Group on Quaternary Interglacials (QUIGS), will conduct a joint, cross-cutting meeting from 24-27 September 2018 in Galloway, New Jersey, USA.
Scientific rationale The overarching goal is to promote cross-cutting initiatives between members of these two communities. In fact, while workshops from these two projects (and their predecessors) were successful and produced a relevant number of products, the commingling of ideas between the two groups was mostly the result of individual initiatives, and few scientists participated regularly in the activities of both groups. With this joint meeting, we aim to foster a more organized collaboration between PALSEA2 and QUIGS that is essential to solve a number of outstanding issues that have been identified by both working groups. These issues include:
Can external (e.g. orbital) or internal (e.g. greenhouse gases) climate forcings explain the observed climate, ice-sheet and sea-level responses based on current knowledge of global physics?
Does the relationship between interglacial climate and ice sheets/sea level change across the Quaternary? Are there interglacials other than MIS 5e and MIS 11 where we could attempt to link climate and sea level?
How do interglacial sea-level highstands relate to interglacial high-latitude, global and tropical temperatures?
Can we reach a firm conclusion on the magnitude of warming and the maximum sea level contribution for Greenland and Antarctic in MIS 5e?
Program This four-day workshop is divided in three main parts: the first two days will be dedicated to talks and posters from the participants, divided in topical sessions. Each participant will be asked to tackle one of the main questions identified above or raise new ones related to both communities. The talk/poster sessions will be complemented by one field trip to nearby salt-marshes (Holocene sea-level indicators) and the Pine Barrens (Late Pleistocene permafrost). The last day of the meeting will be dedicated to (1) discussions focused on the cross-cutting themes between PALSEA and QUIGS and (2) the initiation of cross-cutting activities.
Background The idea for this workshop emerged from discussions between members of the two working groups that highlighted the need for a joint forum to address the identified outstanding issues. During the discussion sessions, each key issue will be addressed in the light of the presented talks and posters, additional cross-cutting themes might be identified and activities involving members from both PALSEA2 and QUIGS will be initiated.
Financial support Early Career Researchers and Researchers from Developing or Low GDP Countries will be able to request support for travel and accommodation during the registration process. This workshop is sponsored by PAGES (Past Global Changes), INQUA (International Union for Quaternary Sciences) and NSF (US National Science Foundation).
